a

Values in parentheses are those for the highest resolution shell.

b

Rmerge = ∑hkl∑i|Ii−〈I〉|∑hkl∑i Ii, where Ii is the observed intensity, and 〈I〉is the average intensity of multiple observations of symmetry-related reflections.

c

R = ∑hkl||Fobs|−k|Fcal||/∑hkl|Fobs|, where Rfree is calculated for a randomly chosen 5% of reflections, and Rwork is calculated for the remaining 95% of reflections used for structure refinement.
